Class CC/CD and Midget Fuse Blocks
600 Volt
Space saving 600 volt, 30 amp molded case fuse blocks with side
barriers for isolation. Class CC blocks and Midget blocks are identical
except Class CC blocks incorporate a rejection feature to assure proper
fusing.
Safety
• Rejection feature — Class CC fuse blocks have a rejection feature
which prevents the insertion of fuses with lower interrupting rating
or voltage ratings. Class CC fuses are rated 600 volts and have an
interrupting rating of 200,000 amperes. Midget fuse voltage ratings
vary and their interrupting rating may be as low as 10,000 amperes.
Note that Class CC fuses may be used in Midget fuse blocks, but Midget
fuses cannot be used in Class CC blocks.
Long life
• High-strength materials — Class CC and Midget fuse blocks are
molded of high-strength, high-temperature material to minimize
block breakage during handling and installation, as well as damage
caused by overheating.
• Reduced resistance, less heat — High conductivity, one-piece copper
alloy fuse clips have lower resistance than traditional two-piece brass
or phosphor bronze fuse clips, which minimizes heat rise and watts
loss within the fuse block.
Reduced inventory
• Gangable — Interlocking fuse blocks allow ganging to produce a fuse
block with any number of poles.
• Flexible terminal arrangements — 30A Class CC and Midget fuse
blocks are available with type C box lug, type SQ screw, or type
PQ pressure plate terminals. Type SQ terminals have binding-head
screws, while type PQ terminals have captive pressure plates. Both
terminal types can accommodate side or top mounted quick-connect
terminals. This flexibility allows the accommodation of most needs
and reduces part inventory requirements.
• 60A CD fuse blocks are available with type C box lug terminals.
• DIN rail mountable — FBDIN1 adapters permit snap-mounting
Littelfuse Class CC and Midget 30 amp fuse blocks directly to
standard or low profile 35mm symmetrical “hat” and 32mm
asymmetrical DIN rails. Patented DIN rail adapters snap securely to
Littelfuse fuse blocks and to DIN rails without tools. They can be
readily removed from rails by lifting the disconnect tab.
• L60060C 60A fuse blocks have patented integral DIN rail adapters
which allow direct mounting to 35mm “hat” type DIN rails.
